Following technique may be used for 10 household

  1. In Package Sewage Treatment Plants for10 household, a modified septic tank as an alternative to a septic tank/fosse septique. The reasons being that despite having plenty of land in which you can install a new septic tank and vertical sand filter, If you do not want to use up too much land, because to use the land for building a new house in a couple of years time. Also sand filters that take the output of septic tanks can often clog up in only a few years, meaning you have to remove all the sand and have it replaced. The sand used in these filters is special filtration sand and quiet expensive.
  1. Biological Wastewater systems from BioKube treat black and grey sewage water. The purified wastewater is safe to reuse. UV and after treatment remove E-coli and Nematodes. Main use is wastewater from villages, hotels, resorts, mines, oil camps and individual houses.
  2. (More than 10,I think small village)

Small villages and remote communities often lack access to wastewater treatment plants with fully developed primary and secondary treatment capabilities. The design and development of new wastewater treatment plants for small communities and remote villages is time and resource intensive. Compared to other issues, wastewater is often seen as a secondary issue and access to funding is not always available or seen as to expensive for a small community.

Water sources are sometimes contaminated with organic or septic matter. Citizens may therefore be confronted with a decline of water quality, pollution of local lakes and rivers, resulting in higher costs for importing of drinking water.

Today, cost-effective small-scale sewage treatment plants for up to 50 inhabitants exist. Using a modular, turnkey construction system, the newest generation of small-scale community sewage treatment plants combines, multi-stage treatment systems and units such as:

· Sequencing-Batch-Reactor (SBR) Processing

· Membrane Reactor using Ultrafiltration

· Continuous-Batch-Reactor (CBR) Processing

· Short-Time-Batch-Reactor (STBR) Processing

· Biofilm Method using growth bodies from plastic

· Vented Biofilters for wastewater treatment

· Fixed-bed plants for wastewater treatment

· Plant based purification systems (etc.)
